Abstract
A axially rotary lathe which has the blade entered automatically without block mainly comprises a frame, a stepless speed regulation motor with a speed adjuster, a belt wheel, a worm and worm wheel, a slide carriage guide, a slide carriage, a dynamic pressure roller, two fixed pressure rollers, a pressure motor, a gear box and a turning cut blade. The stepless speed regulation motor fixed on the frame work by the belt wheel driving the worm and worm wheel. The worm pushes the slide carriage to move on the slide carriage guide. The slide carriage is fixedly provided with the turning cut blade and the dynamic pressure roller. The two fixed pressure roller is fixed on the frame. The dynamic pressure roller and the fixed pressure roller rotate in the same speed driven by the pressure motor through the gear box. The dynamic pressure roller and the fixed pressure roller make the artifactitious log fixed and rotating. Racks provided with gears are fixed on the slide carriage. The gears are connected with a coaxial cam, with which the driven pole rack forms cam framework. The driven pole rack drives gears of the speed modulation machine to rotate. The gears of the speed modulation machine moves together with the knob of the speed modulation machine. So when the diameter of the log is declined, the speed of blade entering of the turning cut blade is automatically accelerated, which guarantees the uniformity of the veneer made by turning cut.
Description
One, technical field
The utility model relates to a kind of autofeed does not have clamp veneer lathe, i.e. veneer lath.
Two, background technology
Because the variation of China's Forest Resources situation, the area of artificial forest strengthens day by day, and the proportion of undersized log is increasing, and the rotary-cut processing of path round log and reel more and more seems important.Rotary trunk-layer stripping machine without clamper is used in the rotary-cut of path round log usually.To cut out the thickness of wood chip veneer be to determine by the size of adjusting the cutter door to the rotary trunk-layer stripping machine without clamper of Xiao Shouing in the market, if a kind of hydraulicdriven peeler, the knot or the hard wood resistance that run on the round log are big, then form withdrawing easily, the veneer became uneven of back-out.Another kind is a machine driving, drives worm and gear by buncher, promotes slide carriage by the screw mandrel rotation and advances, be fixed with cutting knife on the slide carriage, the speed that slide carriage advances is the speed regulator with the Artificial Control buncher, because Artificial Control, feed velocity is sometimes fast and sometimes slow, causes the veneer became uneven of back-out.So all there is the problem of the veneer thickness inequality that rotary-cut goes out in rotary trunk-layer stripping machine without clamper in the market, and can't grasp the unified thickness of veneer in process of production, so the veneer that institute's rotary-cut goes out can only be as multiple-plate central layer, can not be as face, base plate, even be used for the central layer of three-ply board or five-ply board, also can cause three-ply board or five-ply board became uneven, influence the quality of glued board.
Three, summary of the invention
The purpose of this utility model provides the uniform autofeed rotary trunk-layer stripping machine without clamper of veneer thickness that a kind of energy assurance cuts out.
For rotary trunk-layer stripping machine without clamper, its round log pressure roller drives the round log rotation, the rotating speed of pressure roller is constant, because round log is in the rotary-cut process, therefore diameter constantly diminishes, and will guarantee that the veneer thickness that rotary-cut goes out is even, feed velocity is continued to increase with it be complementary, feed velocity is controlled by buncher, and the rotating speed that therefore will constantly quicken buncher in the feed process is even with the veneer that reaches rotary-cut and go out.
The technical solution of the utility model is as follows:
A kind of autofeed rotary trunk-layer stripping machine without clamper, it mainly comprises frame, the stepless speed-regulating motor that has speed regulator, belt pulley, worm and gear, the slide carriage guide rail, slide carriage, dynamic pressure roller, two level pressure rollers, the pressure roller motor, gearbox, the rotary-cut cutter, stepless speed-regulating motor is fixed on the frame, drive the worm and gear running by belt pulley, the slide carriage that worm screw promotes on the slide carriage guide rail moves, be fixed with rotary-cut cutter and dynamic pressure roller on the slide carriage, two level pressure rollers are fixed on the frame, dynamic pressure roller and level pressure roller drive the constant speed rotation by the pressure roller motor by gearbox, its rotation is fixed and driven to dynamic pressure roller and level pressure roller with the round log of processing, on slide carriage, be fixed with tooth bar, is furnished with gear on the tooth bar, gear is connected with a coaxial cam, cam and follower lever tooth bar are formed cam mechanism, the rotation of follower lever rack drives governor gear, governor gear and speed regulator speed governing knob interlock.The distance that the distance that slide carriage advances when the rotary-cut of autofeed rotary trunk-layer stripping machine without clamper waits tooth bar thereon to advance, the diameter that reflects current round log, the distance that tooth bar advances equals arc length mobile on its pitch diameter that cogs again, when pitch diameter known, the radian that can reflect the gear rotation, for feed velocity (being the speed that slide carriage advances) and the speed that processing log diameter diminishes are complementary, therefore adopt and on gear, connect a same axis cam, how many radians gear rotates, how many radians cam also rotates, but the speed of the moving bar tooth bar that cam promotes does not wait, and the radian of cam rotation is big more, and it is fast more to promote the follower lever tooth bar, make speed regulator speed governing knob also change soon more, the faster rotational speed of stepless speed-regulating motor, what worm and gear promotion slide carriage advanced speeds up, and feed velocity is accelerated, the speed that processing log diameter diminishes is fast, feed velocity also accelerates, and has reached synchronously, thereby has guaranteed that the veneer thickness that rotary-cut goes out is even.
Autofeed rotary trunk-layer stripping machine without clamper of the present utility model, stepless speed-regulating motor can drive worm and gear by belt pulley and two change gears (gear), so change the gear ratio of two change gears, can regulate feed velocity, can control the thickness of the veneer that rotary-cut goes out.
Autofeed rotary trunk-layer stripping machine without clamper of the present utility model, dynamic pressure roller and level pressure roller can be driven respectively by speed motors such as two and do the constant speed rotation.
Autofeed rotary trunk-layer stripping machine without clamper of the present utility model can have an independent motor with the reverse running of control worm and gear, and slide carriage is fallen back.
Autofeed rotary trunk-layer stripping machine without clamper of the present utility model since the speed of feed and processed log diameter mate automatically, therefore guaranteed the veneer thickness unanimity that rotary-cut goes out, evenly, and it can change feed velocity to regulate the veneer thickness that rotary-cut goes out by changing change gear.
